What would you do if you had a month left?

[Vbp6US]

Alright guys, I recently bought the car and found out that I have a month of warranty remaining on it so I went to the dealership to get a wheel bearing (hub assembly) replaced as the one on there went bad after 27k miles. It was discovered when I got my tires changed. I asked the service adviser if there are any recalls on the car or service bulletins and he said nope. I need your advice. I hear the ECU sound in my car and while it doesn't bother me, I would rather it didn't exist. What is the best way to approach this issue?

If you had a month of warranty remaining, what would you have them look at? I want them to see if my clutch and transmission are OK. Advice please. I have 28k miles and 3 years is almost gone.

Thanks
